ruby on rails seed .yml file which has models with associations in it -

i don't understand how seed .yml file has more 1 data model in it, plus they interrelated.

that's have:

project.rb

class project < activerecord::base   has_many :todos end 

todo.rb

class todo < activerecord::base    belongs_to :project  end 

my data schema:

  create_table "projects", force: :cascade |t|     t.string   "title"     t.datetime "created_at", null: false     t.datetime "updated_at", null: false   end    create_table "todos", force: :cascade |t|     t.string   "text"     t.boolean  "iscompleted"     t.integer  "project_id"     t.datetime "created_at",  null: false     t.datetime "updated_at",  null: false   end 

seeds.rb (ofc doesn't work)

seed_file = file.join(rails.root, 'db', 'seeds/seeds.yml') config = yaml::load_file(seed_file) project.create(config["projects"]) 

seeds/seeds.yml

projects:  - title: 'family'    todos:     - text: 'get milk'       iscompleted: false     - text: 'cook bacon'       iscompleted: true     - text: 'repair front door'       iscompleted: false  - title: 'work'    todos:     - text: 'call boss'       iscompleted: true     - text: 'finish work tasks'       iscompleted: true     - text: 'get fired'       iscompleted: false  - title: 'therest'    todos:     - text: 'do something'       iscompleted: false     - text: 'ask question on stackoverflow'       iscompleted: false 

can tell me please, should make work properly. need use kind of data seeds.yml, know how make 2 different .yml files projects , todos , make them work, not way want solve problem.

do favor, delete seeds.yml file , create inside seeds.rb
